 ## Installation
 
-_This section is incomplete. Please consider contributing to it._
+Install Traefik via your preferred method. You can read the official [docker quickstart guide](https://doc.traefik.io/traefik/getting-started/docker/) or the [in-depth walkthrough](https://doc.traefik.io/traefik/setup/docker/)
 
 ## Configuration
+You only have to do any one of these methods.
 
-_This section is incomplete. Please consider contributing to it._
+Be sure to change the `your.server.name` to your actual tuwunel domain. and the certresolver should be changed to whatever you named it in your traefik config.
+### Labels
+To use labels with traefik you need to configure a [docker provider](https://doc.traefik.io/traefik/reference/install-configuration/providers/docker/).
+
+Then add the labels in your tuwunel's docker compose file.
+```yaml
+labels:
+    - "traefik.enable=true"
+    - "traefik.http.routers.tuwunel.entrypoints=web"
+    - "traefik.http.routers.tuwunel.rule=Host(`your.server.name`)"
+    - "traefik.http.routers.tuwunel.middlewares=https-redirect@file"
+    - "traefik.http.routers.tuwunel-secure.entrypoints=websecure"
+    - "traefik.http.routers.tuwunel-secure.rule=Host(`your.server.name`)"
+    - "traefik.http.routers.tuwunel-secure.tls=true"
+    - "traefik.http.routers.tuwunel-secure.service=tuwunel"
+    - "traefik.http.services.tuwunel.loadbalancer.server.port=6167"
+    - "traefik.http.routers.tuwunel-secure.tls.certresolver=letsencrypt"
+    - "traefik.docker.network=proxy"
+```
+### Config File
+To use the config file you need to configure a [file provider](https://doc.traefik.io/traefik/reference/install-configuration/providers/others/file/).
+
+Then add this into your config file.
+```yaml
+http:
+    routers:
+        tuwunel:
+            entryPoints:
+                - "web"
+                - "websecure"
+            rule: "Host(`your.server.name`)"
+            middlewares:
+                - https-redirect
+            tls:
+                certResolver: "letsencrypt"
+            service: tuwunel
+    services:
+        tuwunel:
+            loadBalancer:
+                servers:
+            # this url should point to your tuwunel installation.
+            # this should work if your tuwunel container is named tuwunel and is in the same network as traefik.
+                    - url: "http://tuwunel:6167"
+                passHostHeader: true
+```
